VIAIR 450P Review

Characteristics of VIAIR 450P

1066409This Compressor saves your time because you avoid time for cooling it down, which can take 40 minutes. Other compressors don’t have such a wonderful trait and probably it is the best feature of this product. This Compressor fills large tires much faster than other devices and in five minutes you can inflate with pressure 15 to 30 PSI the tire of 37″ x 12.5″. And at a pressure of 0-30 PSI the process to fill tire of the same size takes seven minutes.

1066409At 100 PSI it has volume flow rate (CFM) 0.94, at the same time construction of the device is built the way so it can deal with low pressure in the tire, which doesn’t drive the pneumatic tool. It can also be driven with a magnetic motor, which can give 150 PSI working pressure maximally. The compression system is protected from excessive pressure by a switch. Additionally, this switch automatically turns the motor off, but this function works when the pressure inside reaches 145 PSI (this is so called factory set cut-out pressure). When the pressure diminishes to 120 PSI, the system will restart its work according to the program.

1066409When you pumped one tire and need to move to another, you will find the inbuilt automatic shutdown function of the compressor very useful. There is a handy function in the compressor, which allows you not to turn it off when you pump up the tire, it is not available in classic portable compressors. More than that, it is turned off when it doesn’t intensively inflates the tire, this way it will store effort and time to fill up the tire quickly. Moreover, this function permits to control pressure inside the tire during its filling.

1066409There are some useful details, which come together with the 12-volt unit. Among others it includes a gas station-type tire gun of 200 PSI. With the pressure gauge of the inflation gun you can control pressure on the fly.

1066409This is convenient when you want to manage the process of filling the tire with air. The necessity to go back and forth from a gauge and a tire chuck to see how air pumping works. This peculiarity of the Compressor excludes necessity of the extra pressure gauge. This way you get possibility to deflate and inflate the tire without problems. Last but not least, tire pressure can be regulated (lowered) with a valve button, which is located in the gun kit.

1066409The Compressor comes with three PC pumping tips kit, an extension hose of 25 ft long, and diamond plate sand tray, which is resistant to vibrations. The hose makes it possible for you to reach all tires of your car or bike, and you don’t have to move the unit. Additionally each end of the coiled house is provided with a 1/4″ fast connect coupler. Nice feature, which is supplied with the Compressor is an extra carry bag with a zipper section for the deflator and inflator hose. It would be better if it was a hard case, but a carry bag is still good and a bonus for customers.

1066409To link up the Compressor to the battery terminal of the car a dual battery system is used. Maximally 12 volt power supply can be used to connect the battery directly. To keep the batteries charged and not appear in the situation when it is down it is recommended to keep the car’s engine working while the tires are inflated. The upper limit of allowed current is 23 amperes and at this current strength you reach the highest pressure. One more good point, the inline fuse holder saves the unit from spikes.

w256h2561339252558DeleteRedEight-inch long power cord of the air compressor and 25-inch long hose allow reaching the tires at long distance.
